FIG. 35. The pattern of bristles in the first left femur of fifth instar Rhodnius
larvae. A and C: The number of bristles in the length has been reduced, but other
proportions have been maintained. The cylindrical leg is shown flat as if it has been
opened by a dorsal longitudinal cut. Squares of integument were excised and transposed as shown. B: The effect upon the adult pattern of transposing pieces of
integument laterally around the femur in the fifth stadium. There is little distortion. D: The effect upon the adult pattern of transposing pieces of integument
longitudinally in the length of the femur in the fifth stadium. There is considerable
distortion with a rearrangement of the pattern and orientation of bristles. The folds
which arise around the grafts are not represented.
